To entitle any copy of a law published in the Revised Statutes of 1964 to be read in evidence, there shall be contained in the same book a printed certificate of the Secretary of State that such copy is a correct transcript of the text of the original laws. A facsimile of the signature of the Secretary of State imprinted by or at his direction upon such certificate shall have the same validity as his written signature.   [PL 1965, c. 425, §1 (NEW).]
